In a number of debug cases, the DMA-based trace can add problems (e.g. with HDaudio channel allocation). It also generates additional traffic on the bus and if the DMA handling is unreliable will prevent audio use-cases from working normally. Using the trace also requires tools to be installed on the target. The trace can be instead handled as dynamic debug. We can use a Kconfig to force the trace to be enabled in all cases, or use a module parameter to enable it on a need-basis, e.g. by setting "options snd_sof sof_debug=0x1" in a /etc/modprobe.d file.
